Welty, Youngstown, Ohio, assignors to Carbonic Dispenser, lnc., Canfield, Ohio, a corporation of Ohio Application March 13, 1951, Serial No. 215,205 Claims. (Cl. 137-628) This invention relates to the art of dispensing liquids and more particularly to the dispensing of carbonated beverages such as beer and soft drinks, for example.

It is an object of this invention to provide an improved valve of this nature which is pense the syrup and carbonated water components of soft drinks in a uniform manner and with a minimum loss of carbonation. In the interest of conserving space, and especially since the development of compact and effective carbonating apparatus, it has'been found desirable, in many soda fountain and tavern dispensing installations, to utilize the syrup concentrate of the various types of soft drinks along with a single source of carbonated water, rather than the relatively bulky form of the premixed drinks. Heretofore, however, it has been a problem of considerable magnitude to provide a bonation. As may be understood, the two conditions work directly against each other, since a certain degree of turbulence, necessary to obtain a uniform mix of the components, causes considerable loss of carbonation at the low dispensing pressure. We have therefore provided a valve of such design as to mitigate the counteracting clfects of the mixing and decarbonation.

It is another object of .this invention to provide an improved valve of this type wherein are combined several independently operated syrup dispensing valves which act cooperatively with a single valve for the control of carbonated water to automatically dispense a properly mixed beverage upon actuation of any of the independently operated syrup valves.

It is yet another object of the invention to provide a valve having the characteristics enumerated above which is compact to the degree that it requires but little more space than that required by a similar valve having provisions for dispensing but a $211816 flavor.

A furtherobject of our invention is the provision of an improved valve of the character described which is of such inherent versatility that minor adaptations will render it capable of dispensing uncarbonated beverages, such as fruit ades or uncarbonated water for example, along with various carbonated beverages from other of its several outlets. It is also an object of the invention to provide a high pressure soda dispensing valve which is operated independently of the syrup valves but by an operator which is utilized for one of said syrup valves.

A still further object of our invention is the inclusion in our valve of an element which is operative to provide a surge trap for carbonated water emitted at relatively high velocity from a restricted pressure reducing passage. Our novel element. further provides a somewhat restricted cup by means of which the carbonated water is forced to surround the syrup valves as it is issued from the valve, thus insuring uniform mixing of the components and further insuring that the syrup valves will be thoroughly washed by the water after closing of the valves.

The above and other objects and advantages of the invention will become apparent upon full'consideration of the following detailed specification and the accompanying drawings wherein there is disclosed a certain preferred embodiment of the invention.

In the drawings:

Figure 3 is a horizontal section taken along line IIIIII of Figure 2; and t Figure 4 is a horizontal section taken along line IV-IV of Figure Referring now to the drawings, and in particular to Figures 1, and 2 thereof, the reference numeral 10 de- I notes a generally cylindrical block which forms the main 0 operating levers 27, 28 and 29 or body portion of our valve. Rigidly secured to the body 10 by welding or other suitable means, not shown, is a tubular support 11 which extends outwardly of the body 10 in normal relation to the axis thereof. The support 11 is normally provided with means, not shown, by which it may be secured to a dispensing panel or cooling tank as may be understood. In the embodiment shown we have provided three vertical bores 12, 13 and 14 which are spaced as shown in Figure 3. The bores 12-14 are enlarged at their upper and lower end portions and are reduced centrally as shown in Figures 1 and 2.- Slidably charge the syrup at a point considerably below the lower end of the body member 10. To accomplish this we provide tubular extensions 18 which are adapted to be rigidly retained in the lower enlarged portions of the bores 12-14 and which depend downwardly therefrom in spaced concentric relation to the plungers 15. The lower ends of the tubular extensions 18 are adapted to seat the resilient washers 17 to thus, in cooperation therewith, form a liquid-tight seal. In order to provide a normally closed valve we utilize compressible coil springs 19 which are positioned over the plungers 15 and act upon the enlarged heads 20 thereof to yieldably urge the said plungers upwardly. Also acted upon by the springs 19, at their lower ends, are metal washers 21 and resilient O ring washers 22 which prevent the upward passage of syrup into the upper enlarged portrons of the bores 12-14. As may be observed from Figure 3 the syrup is supplied to the lower enlarged portions of the bores 12-14 by means of horizontal bores 23, 24 and 25 respectively which are connected to conduits 23', 24' and 25' respectively. The said conduits 23'-25' communicate in the conventional manner with pressurized sources of syrup flavoring, not shown.

Inasmuch as the relatively short length of the reduced central portion of the bores 12-14 is insuilicient toprovide proper guidance for the plungers 15, we have devised insertable guide pieces 26 which are secured to the bottom of the plungers 15 by means of the cap screws 16 and which have a plurality of circumferentially spaced upwardly extending legs. The upwardly extending leg portions of the guide pieces 26 are so dimensioned to slidably retain the plungers 15 in spaced concentric relation to the tubular extensions 18 and yet provide for the relatively unrestricted flow of syrup from the valves.

To open the normally closed syrup valves it is of course necessary to force the plungers downwar ly against the action of the springs .19. To this end we provide each of which is adapted to actuate a separateplunger 15. As shown, the levers 27-29 are pivotally mounted on a rod 30 which is secured at each end by lugs 31 fastened to and extending upwardly from the body 10 in diametrically opposed relation. The levers 27 and 29 each have cam surfaces such as is shown at the lower portion of the lever 28. The cam surfaces of levers 27 and 29 overlie the plungers 15 which are retained in bores 12 and 13 respectively and. as may be observed, drawing the upper ends of the said levers forwardly will cause the above mentioned plungers to be It is, of course, may be operated their seats-the tubular extensions 18. understood that the levers 27 and 29 tion thereto.

independently of each other and of the center lever 28, and that each of the plungers 15 is thus operated independently of the others.

For reasons which will become apparent upon further consideration of this specification the plunger 15 which is retained in bore 14 is positioned substantially out of line with respect to the axis of the rod 30 which serves as a pivotal mounting for the operation levers 27-29. Due to the aforesaid positioning the actuating cam surface of the operator 28 cannot act directly upon the plunger retained in the bore 14. To overcome this we have provided a short bar 32 which is operative to move vertically while maintaining a horizontal disposition. The inner end of the bar 32 is retained in a recess provided therefor in an inverted cup member 33 which is slidably received 1 in the body member in substantially concentric rela- As shown in Figure 2, forward movement of the operating lever 28 will cause the bar 32 and thus the cup member'33 to move vertically downward. As may be observed, the bar 32 may move freely for a short distance whereupon it comes into contact with the plunger over which it is positioned. After the said contact has been made the plunger moves downwardly with the bar 32 into the open position. 1

To insure proper guidance of the bar 32 in its vertical movement we provide a short pin 34 which is normally retained in a mating bore provided in the outer portion of the bar 32.

In accordance with the principles of the invention we have provided a single carbonated-water val 1e which may be operated by each of the three levers 27-29 so that carbonated water will be automatically dispensed along with syrup flavoring. The said carbonated water valve includes an internally tapered tubular insert 35 which is rigidly retained in the lower portion-of the body 10 in centrally'disposed relation thereto. The lower end of the insert 35 is threaded internally to receive a tapered plug 36. As shown in the drawings, a small clearance is provided between the two parts 35 and 36 to form a relatively restricted passage through which the carbonated water must flow to be discharged. As is well known to the art such restricted passage is provided as a means of reducing the necessarily high pressure of the carbonated water so that it may be readily dispensed without undue loss of carbonation. In the interest of obtain ing optimum performance under conditions which are likely to vary in each particular installation, the restricted passage should be accurately adiustable. According to principles disclosed in our copending application, Ser. No. 97,409, filed June 6, 1949, now Patent No. 2,653,055, the use of a tapered plug having a screw-threaded axial adjustment provides a restricted passage having such accurate regulation.

Communicating between the bores provided for the reception of the tubular insert 35 and the inverted cup member 33 is a relatively small diametered bore 37 which is in communication with a source of carbonated water, not shown, by means of an intersecting bore 38 and conduit 39. As may be observed, a vertical here has been provided in the upper portion of the tapered plug 36 for the reception of a compressible coil spring 40. A valving piston 41, carrying a resilient washer 42 at its upper end, is slidably received in the said bore and is urged upwardly by said spring 40 into contact with the horizontal shoulder formed at the junction of the bore 37 with that provided for the reception of the tubular insert 35. As means of operating the valving piston 41 we provide an actuating rod 43 which is screw-threadedly connected to the piston 41 and which extends upwardly through the bore 37 in spaced concentric relation thereto. The upper end of the actuating rod 43 is enlarged for slidable contact with the bore 37 and is provided with an annular recess for the reception of an O ring washer 44, the purpose of the washer 44 being, of course, to prevent the passage of the carbonated water upwardly past the enlarged portion of the actuating rod 43. As shown, the upper end portion of the rod 43 projects above the body member 10, and supported thereon is the inverted cup member 33. It will be noted, then, that downward movement of the cup member 33 will cause the opening of the valve to permit the flow of the carbonated water. It will be further noted that the cam surface of each of the operating levers 27- 29 at least partially overlies the cup member 33 so that upon actuation of any of the said levers 27-29 carbonated water as well as the particular choice of syrup will be caused to flow. Experimental determinations have shown the proper size of valve opening to be used to obtain the proper mixture of the components and this, of

course, must be strictly adhered to if a drink of the correct proportions is to be obtained.

Secured to the lower end of the body 10 so as to form a fluid-tight seal therewith is a liquid trap 45, the function of which is to arrest the flow of carbonated water issuing from a plurality of radical apertures 46 provided in the tubular insert 35. As will be understood the carbonated water emerging from the restricted passage formed by the members 35 and 36 will be moving at a relatively high velocity and will be at substantially atomspheric pressurcsconditions which are very conducive to the loss of carbonation. By the provision of an enlarged liquid trap at the exit of the restricted passage we provide means of reducing the velocity of the stream and of preventing excessive loss of carbonation by causing the stream to smother itself in the enclosure.

Depending integrally from liquid trap 45 are conical drip cups 47 which are positioned about each of the syrup valves as shown, with the lower or outlet ends of the tubular extension 18. As may be observed, the conical drip cups 47 provide the only outlet for carbonated water issuing from the radial apertures 46 of the tubular insert 35 so that the water will be discharged at the same point as the syrup to thus obtain thorough intermixing of the components. As regards the mixing of the fluids. particular attention should be focused upon the small clearance provided between the lower end of the drip cups 47 and the washers 17 of the syrup valves, and to the relative positioning of the lower end of the drip cup 47 with respect to the syrup outlet as defined by the lower end of the tubular extension and the upper surface of the washer 17. By providing a small clearance between the parts 47 and 17 we insure a relatively restricted flow of water about a closed valve while permitting a greater flow about an opened valve. As will be noted, the opening of a syrup valve creates a larger clearance through which the water may pass. Thus uniform mixing of the liquids is furthered by having a major portion of the carbonated water pass around that particular valve which is discharging syrup. In addition, it will be noted that the inward tapering of the conical cups 47 provides a certain degree of impingement of the water upon the outwardly moving syrup. This action further insures uniform mixing of the fluids. There is little loss of carbonation at this point. however, since the water is moving at a relatively slow gravity fiow.

A further effect of restricted opening between the cup 47 and syrup valve is that water is retained in the cup for a short time after the operating lever has been returned to the upright position to close the syrup and water valves. This feature provides that the syrup which would ordinarily be retained around the valve opening is dissolved and washed away by the trapped water, rather than left to congeal and impair the operation of the valve. To further the washing action we provide that the valve controlling the flow of carbonated water be opened slightly before, and remain open for a short time after, the syrup valve. This is easily accomplished by providing for a certain degree of lost motion between the operating levers and their respective syrup valves, while having substantially none between the said levers and the water valve. This construction should be apparent from Figures 1 and 2 which show a. substantial clearance above each of the plungers 15.

In the embodiment of our invention shown herein we have incorporated a means of discharging carbonated water at high velocity, such as would be desired in the preparation of sodas and phosphates, for example. The valving elements of this last mentioned means are in general similar to those of the previously described water valve and the corresponding parts will therefore be referred to by corresponding primed numerals without further description. The vertical bore 37', as shown, intersects the bore 38 to provide communication with the supply of carbonated water, not shown, via the conduit 39. A seat for the washer 42' is provided by the upper end face of a vertical bore 48 at the point where the said bore 48 communicates with the vertical bore 37'. Threadedly engaging the bore 48 is a fitting 49 which has a bore therein for the reception of the coil spring 40,

and which carries at its lower end a discharge tube 50; As should be apparent, opening of the valve by downward movement of the rod 43 will allow the discharge of relatively high pressure carbonated water through the tube 50. To accomplish downward movement of the rod 43 we provide a foot 51 at the lower and rearward portion of the operating lever 28. Theioot 51 is adapted to overlie the upwardly extending portion of the rod 43' so that rearward movement of the lever 28 will cause downward movement and consequent opening of the valve. It will be 'noted that the returning force of the spring 40' acts at a considerable distance from the pivotal center of the operating lever 28 and is therefore effective, upon release of the lever to return it to its normal position and close the valve.

It should be noted that while the restoring force applied to the rod 43' is operative to return the lever 28 to the normal or upright position, the restoring forces of the various syrup valves and the centrally located water valve act directly through the center of the pivot rod 30 and therefore have no tendency of return the levers 2729 to the normal from the forward position. This provision has been made purposely since this type of operation has been found to be most satisfactory in most instances. To further insure that the levers 27-29 do not restore them selves or otherwise move on their own accord we provide each with a resilient O ring washer 52 which is operative to increase the friction between the said levers and the stationary pivot rod 30. It will be understood, of course, that self-restoring characteristics may be incorpoiated by merely altering the cam surfaces to the extent that the restoring forces of the valves are applied at a point forward of the pivot point of the levers.

To provide an upright reference position for each of the levers to which they may be returned when closing the valves, each of the levers 27 and 29 has been provided with a foot similar to the foot 51 of the lever 28. The upper surface 53 of the body then serves as a positive stop for the return of levers 27 and 29. The lever 28 will of course be stopped upon its foot 51 contacting the upper end of the rod 43, although sutficient additional pressure will permit further movement of this lever to open the high pressure water valve, as explained.

To complete the assembly and to enclose the principal parts of the dispensing valve for the sake of outward appearance we. provide a discharge funnel 54 which has a single central outlet for the discharge of liquid from the various valves. A cap 55 encloses the upper end of the assembly and houses the levers 27-29. Suitable slots are, of course, provided in the cap 55 to permit movement of the levers as required.

From the foregoing disclosure it should be apparent that we have provided apparatus for the dispensing of .carbonated beverages and the like embodying several novel principles of operation and construction which render it desirable from the standpoint of manufacture as well as that of use. We have in the embodiment herein described incorporated five individual valves into a compact and practical structure, the construction of which necessitates only elementary machining operations.

In our valve we have incorporated numerous features deemed desirable by consumers of such devices. Further, our novel liquid trap element with its integral drip cups insures proper delivery of the carbonated waterwith a minimum loss of carbonation. Into the drip cups themselves we have incorporated features which insure proper and uniform mixing of the constituents by causing the major portion of the carbonated water to pass around the valve from which syrup flavoring is being issued while substantially limiting the flow of water around the closed valves. We have also, by means of the aforementioned drip cups, provided aunit which is self-cleaning in operation. The relatively restricted passage between the'drips cups and the closed syrup valves causes the retention of a small amount of the carbonated water after the closing of the valves. The thus retained water passes slowly out of the cup, and in doing so dissolves and washes away any syrup which may have been retained at the valve opening. The self washing action is furthered by providing that the water valve open before and close after the syrup valves. It should be understood that by incorporating the last mentioned features we substantially eliminate undesirable crosscontamination of the various flavors and insure a pure drink.

A further advantage of our valve is its versatility. 'As

mentioned previously, minor adaptations may be made in the structure to permit the dispensation of plain water or other uncarbonated beverages such as fruit ades, for

example. This may be accomplished by merely recessing the actuating cam surface of one or both of the extreme operating levers 27 and/or 28 so that it will not bear upon the inverted cup member 33. Thus conduits 24' and/or 23' may be connected to any suitable pressurized source of plain water or other beverage to permit the same to be dispensed free of carbonation.

The incorporation of the short bar 32 as a means of actuating a remotely positioned syrup valve is a novel principle of operation by virtue of which our valve may be constructed in such a compact and self contained manner. As may be understood, this same principle may be utilized in producing a similar v'alve having four, five, or more syrup flavors as may be desired in some cases.

It should be understood, however, that the embodiment of our invention herein shown and specifically described is illustrative only as many changes may be made in the specific structure without departing from the spirit of the invention. Reference should therefore be had to the appended claims in determining the scope of the incarbonated water valve, conical drip cups, one for each of said syrup outlets, depending integrally from said cup-like'member and surrounding said syrup outlets in closely spaced concentric relation, said drip cups providing the only openings from said chamber for the discharge of carbonated water, the arrangement being such that a relatively restricted water outlet is formed between said drip cups and said syrup outlets whereby said sytl'up outlets are washed during eachoperation of the va ve.
